. RAILROAD-TRACK SWITCH.

Specification of Letters Patent. Patented NOV. 26,1918.

Application filed February 20, 1917. Serial No. 149,968.

To all whom it may} concern:

A Be it known that we. ROYAL A. MGCLURE, CARL H. REEVES, and WILLIAM W. BoULToN, citizens of the United States, residing, at Seattle. in the county of King and State of Washington, have invented a new and in Railroad-Track Switches, of which the following is a specification.

This invention relates to improvements in switches for railroad trackwavs of the single'rail type and the object of this improvement is to provide a simple, reliable and easily operated switch apparatus of this class for making;- connection between a single rail track and a siding or turn out that is connectedwith such track.

I This switch is desim ed for use in connection with the elevated railwav track disclos d in our co-nending ap licat on of R. A. McClure. C. H. Ree es-and W. W. Boulton. filed Februarv 20. 1917. for el at d railwav tracks. and in connect on with the car truck descri ed in t e co-nend sz application of Roval Aj McClure. Henrv R. Steve s and W lliam R ulton'. for trucks for relevated railways; filed February 20. 191

i The inve t on consists in the o el com struc ion. ada tat on and c mb nation oi sw tch mechanism a d tr ck sections as will be. mo e, clearlv hereinafter described and cla m d.

In H accornn nvinrr dmwimrs Finr 1 i a 51 View F a, sw tch co structed in ac- (jopdannn with this invention as it, ah'nparq in on os t o ic". 2 s a sim ar iew of the switc in another no itio Fin. 3 is a enlarx ed view nartl n ect on and nar v in lnvgtion sub tajntiallv' ()n brolzen l e 3. 3 Of Wi '1 and F 4 is an enlaro' d iew nartlv i coctiofl a d n rtlv in e on substantia lv on broken line 4. 4; of Fig.1.

Referring to the drawings throu hout which ke reterence num rals ndicate like arts the numerals 5 and 6 indicate rails in the mainline of a one rail track and 7 indicates the rail of a sid m or turn out asso-' eluted with the main track.

8 is a straight rai ection that is normallv adapted to connect the ends of the rails 5 and 6 as shown in Fig. 1, and 9 is a curved rail section that may be turned into a suitable position to connect the rail 5 with the siding rail 7 as shown in Fig. 2. v

I The rail sections 8 and 9 are rigidly c0nnected with each other by transverse tie/rods 10that are securedby nuts 10' to suitable brackets on thebottoms of the track sections 8 and 9 as shown in Figs. 3 and 'so that the distance between the rail sections '8 and 9 mav be adjusted.

The section 8 is pivoted as at 11in aline ment with and adiacent to the end of the rail 6 and the ends of all of the track sections 5. 6, 7. 8'. and '9 are cut on circumferential lines having the pivot 11 as a center 'so that when the switch comprising the sections 8 and 9 is moved about the nivotll the section 8 mav be. moved into alinex'nent with thera ls 5 and 6 to form a'str ai eht track and when the sect on 9 is moved so that. its end registers with the end of the rail 5 a track conne t on between the rail 5 and the sidi g ra l 7 will be estab i hed and the section 8 will. be. thrown out of line.

' Th switch mechani m s mounted on any su ble base or sunnort 12.

The ce tral nort ona d ou r e d portions of the ra l sect o s 8 and 9 are upported upon rollers 13 that ar pi o d to th bo tom sides of such ec ions a d a ted o roll u o curved traclz a s 14 a d 15.

The e d of th sec ion 9 ad ace th din" rai 7 is suppor ed n conical o l s 16 that roll between the bo om surtacc at a benrino' plate 17 on the rail gnfl'the-ihclih d ton urt e ot a bearimr plate 18 on the ba e 1). th rol rs 16 thus ha ino a trave equal too e h he distance of travel of the end Of the rail 9.

The hear no' late 18 is secured to th a e 1 b bolts 19' that nass thrmurh lott d hol s .20 in such ma iner that the'bearing plate rnav be s ifted sidewise'tora se'or lo er the end of the rail 9 so that it will 'be fl with the top surface of the siding rail 7.

Anv desired means for mov n the switch from the position shown in Fi 1 to the position shown in Fig. 2 mav be used. the mechanism shown in the drawings for acthat is secured to the bottom side of the switch rails and adapted to be engaged by a pinion 22 on a shaft 23 that may be connected with a motor (not shown).

The switch moving mechanism will be so constructed that it will be impossible for the switch to be stopped in an open position and means for closing an electric circuit and throwing the switch will be provided in each of the track members 6 and 7 at a distance from the switch so that a car approaching on the track- 6 will automatically cause the switch to be thrown into the position shown in Fig. 1 and a car approaching on the track 7 will auton'xatically cause the switch to be; thrown into the position shown in Fig. 2 thus making it impossible for a carto runinto an open switch.

The tracks 1% and 15 are preferably ordinary light weight railroad rails and the rollers 13 are flanged so that they will stay on such tracks and not be de-railed by stones,

dirt and the like that may be deposited on such track by accident. v

The tracks 14; and 15 andthe rack 2L are all curved oncircumferential lines described frompivot point 1-1.

While the main line formed by the tracks 5, 6 and 8 is-herein shown as a straight or tangent section it isobvious that the same may be curved, if it is desired to provide a siding in connection with a curved section of track.

It is obvious that this invention is not limitedin its scope to the exact form shown and that changes in the form of construction and arrangement of parts maybe resorted to within the scope of the tel-lowing claims.

What we claimand desire to protect by Letters Patent is:

l, The combination with divergent single rail tracks, of a switch section comprising two track members secured together in spaced relation and movable on a common pivot at the endof one of said track members to selectively establish continuous rail connection in either of said divergent tracks. A 2. The combination with the main line and turnout of a single rail track, of a switch section comprising two track members rigidly secured together in spaced relation and movable on a common-"pivot located on the end of said main rail in ali ne ment with said maintrack to selectively establish continuous. rail connection in said main line or said-W1 1i out.

3 The combination withthe main line and turn out of asingle railtrack, of a Copies of this patent may be obtained'for bers rigidly secured together in spaced relation and movable about a common pivot onl the axis of said main line to selectively establish continuous rail connection with said main line or said turn out, rollers supporting said switch section and trackways for said rollers, said trackways being arranged circumferentially of said pivot.

a. The combination with the main line and turn out of a single rail track of a switch section comprising two track mem bers rigidly secured together in spaced relation and movable about a common pivot loouted near the end of the main line switch member whereby said switch section may be moved to establish a-continuous rail connee tion in said mainline or said turn out, rollers supporting the outer ends of said switch section, circumferential trackways for said rollers. roller bearings supporting the inner end of said turn out switch section and means comprising a bearing plate havingan inclined surface for adjusting the elevation of theinner end of said turn out switch.

5. The combination with the main line and turn out of a single rail track, of a switch comprising a turn out rail section and a main rail section rigidly secured together in spacedrelation, a pivot at one end of said main rail section about whichsaid switch may be turned said pivot forming a center upon whose circumferential lines the ends ot all of said rails are cut so that when said switch section is turned about said pivot the ends of said switch rail sections will register with the ends ofsa-id main line and turn out rails.

(5. The coniibination-withdivergent single rail tracks, of a switch section comprising two track members secured together in spaced relation, a pivot about which said switch member may turn to selectively establish continuous rail connections in either of said divergent tracks, roller bearings supporting said switch member, circumferential tracks for said roller bearings, and power actuated means for moving said switch section.
